Ajay and Bhanu invested in a business in the ratio of 2:5, if 50% of the total profit is goes to charity and Ajay's share is 18 lacs, the total profit is Rs………. Lakhs .

Ajay and Bhanu invested in ratio 2:5, so their profit share ratio is 2:5. After 50% goes to charity, remaining 50% is shared. Ajay's share of remaining profit = (2/7) × 50% = (1/7) of total = 18 lakhs. Therefore total profit = 18 × 7 = 126 lakhs. Alternatively: Total remaining = 50P, Ajay gets (2/7)×50P = (100P/7) = 18, so P = 126.
